Front

Open or closed?

Back

Open

Answer explanation

The correct choice is 'Open'. It is the opposite of 'Closed'.

Front

What type of circuit is shown in the picture?

Back

Parallel Circuit

Answer explanation

The circuit shown in the picture is a parallel circuit, where multiple components are connected in parallel to the same voltage source. This allows current to flow through each component independently.

Front

This steel paperclip would allow electricity to flow through it because:

Back

it is a conductor

Answer explanation

The steel paperclip allows electricity to flow through it because it is a conductor.

Front

Does this diagram represent a series or parallel circuit?

Back

series circuit

Answer explanation

This diagram represents a series circuit. In a series circuit, the components are connected in a single path, and the current flows through each component in sequence.

Front

What are three things all circuits must have?

Back

Power source, conductor, load (light bulb)

Answer explanation

All circuits must have a power source, conductor, and load (light bulb) to function properly.

Front

What is the function of a resistor?

Back

Limit current flow

Answer explanation

A resistor limits the flow of current in a circuit, ensuring that it does not exceed a certain value. In this case, the correct choice is 'Limit current flow'.

Front

Resistance is...

Back

What "slows down" electrons

Answer explanation

Resistance is the property that slows down electrons, making it the correct choice.

Front

What characteristics impact resistance of a material? Thickness, Temperature, Length, All of these

Back

All of these

Answer explanation

The resistance of a material is impacted by its thickness, temperature, and length. Therefore, all of these characteristics affect the resistance.
